My SO's son (near 40 YO) had an Alaskan Malamute for 18 years. He fed the dog only human food every day of its life. When I say human food, I'm not talking about table scraps. He cooked a separate meal for the dog every night. If he didn't have time, he'd stop by a restaurant and order it a steak dinner. When he went away, he cooked and froze meals for the dog. Dessert every day was M&Ms. 18 years old when he finally gave up the ghost.
According to some, he did everything wrong. How long do you suppose this dog would have lived if he did all the "right things".
Excellent point. As long as you mix up things and make sure the dog is getting all the right nutrients he will do better on human food than most of the dry dog foods out there. And because human food typically isn't cooked at 600 degrees, it is easier to digest and processed much better by the pet.
Eighteen years though... that's a good long life by any dog's standards.
